The bill proposes significant changes to Colorado's rainwater collection laws for single-family and small multifamily residences (up to four units). Currently, residents are limited to collecting a maximum of 110 gallons of rainwater, which can only be used for outdoor purposes such as lawn and garden irrigation. The new legislation seeks to remove this 110-gallon cap, allowing homeowners to collect an unlimited amount of rainwater. Additionally, it would lift existing restrictions on the use of collected rainwater, permitting its use for any purpose on the property, including indoor uses. This change aims to provide homeowners with greater flexibility in utilizing rainwater, potentially reducing reliance on municipal water supplies and promoting water conservation.
Summary
Current law authorizes the collection of rooftop precipitation from
a single-family residence or a multifamily residence with 4 or fewer units (small residence). The bill removes the 100-gallon limitation on the amount of rooftop precipitation that may be collected from a small residence and removes all limitations on how the collected precipitation may be used. The bill allows for collection of any amount of precipitation for any use on the property of a small residence.
